Description
12mm Tube-to-Tube Straight Coupling
Professional-Grade Push-Fit Pneumatic Connector
Engineered for precision and reliability, this 12mm tube-to-tube straight coupling delivers instant, leak-proof connections in demanding pneumatic applications. The push-fit design eliminates the need for tools, reducing installation time while maintaining professional-grade performance standards.
Technical Specifications
- Tube Diameter: 12mm (both ends)
- Connection Type: Push-fit / Push-to-connect
- Configuration: Straight inline coupling
- Material: High-grade engineering polymer with precision seals
- Operating Pressure: Suitable for standard pneumatic systems
- Temperature Range: -20°C to +80°C
- Barcode: AC015014875115511
Key Features
- Tool-Free Installation – Push-fit design enables rapid connection without spanners or crimping tools
- Leak-Proof Seal – Precision-engineered O-ring ensures reliable, airtight performance
- Instant Disconnect – Release collar mechanism allows quick tube removal for maintenance or reconfiguration
- Vibration Resistant – Secure grip prevents tube blow-off in high-vibration environments
- Corrosion Resistant – Durable materials withstand workshop conditions and compressed air moisture
Professional Applications
Ideal for extending pneumatic lines, repairing damaged sections, or creating custom air distribution networks in:
- Workshop air tool systems
- Automotive service bays and tyre inflation stations
- Manufacturing and assembly line pneumatics
- Fleet maintenance facilities
- Industrial automation and control systems
- Mobile compressor setups and temporary installations
Installation Guide
- Prepare the Tube – Cut tube squarely using a proper tube cutter. Ensure the cut is clean and perpendicular.
- Check the Tube End – Remove any burrs or debris. The tube end must be smooth for proper seal engagement.
- Insert Firmly – Push the tube into the coupling until it bottoms out against the internal stop. You should feel positive resistance.
- Test the Connection – Gently pull the tube to confirm it's locked. Pressurize the system and check for leaks.
- To Disconnect – Press the release collar while pulling the tube straight out.
Compatibility Notes
This coupling is designed for use with 12mm OD (outer diameter) pneumatic tubing including:
- Polyurethane (PU) pneumatic hose
- Nylon (PA) tubing
- Polyethylene (PE) air line
Note: Ensure tube hardness and wall thickness are compatible with push-fit fittings. Soft or thin-walled tubes may not seal correctly.
